The variation of terminal potential difference (V) with current flowing through a cell is as shown. The emf and internal resistance of the cell are

Answer»

`6 V, 2Omega`
`3 V, 2 Omega`
`6 V, 0.5Omega`
`3 V, 0.5 Omega`

Solution :(d): The equation of TERMINAL potential difference of a CELL is given by, V = E – IR When I = 0, V = 3 V,
`:.` E = V = 3 V
When V = 0, I = 6 A `rArr` r = `E/I = 3/6 = 0.5 Omega`
